This kind of safty seals work by the jar being vacuum sealed with a metal lid that wants to be in “button up” position, but it vacuumed down. Once the vacuum has been broken (jar opened), the button-metal-lid is now up and “pops” when he pushes down on it.

Would have been funnier with an ice cream sundae and a jar of cherries… Get it? Get it?

Yeah, I’m agreeing with Bill here. He’s not “pressing down” on her button, he’s just flipping off her veil. It’s a really cute idea for a comic, I love the *intent*, but either the artist doesn’t actually understand how those lids work or we’re missing something.

He’s accidentally (or maybe “accidentally”) pressing the button as he lifts the veil and his hand brushes over it. I read this comic regularly, and you aren’t the only one that was confused by this one, Bill. He made a news post shortly after it was published explaining it to people who didn’t get it.

I think the bigger issue here is violence towards jam jars; as it seems he has already struck her for mixing it up before their wedding. Is this the sort of abusive relationship we want to see in our lunch pails?
